If i sell mine, it'll be for a sensible diesel
Woody's got the best suggestion here, sell the ///M and buy a house.
I get the feeling my current car will be the last of my fun cars. I've always seen cars as money down the drain, which in the last 10 years has been fine, but now im shaping up to move to a bigger house and settle down its not justifiable at all.
For all those thinking of upgrading your Z4's to Z4M's: Suprisingly the biggest thing I found was aesthetic. I love the bonnet ridges, the interlagos blue and the 4 exhaust pipes etc etc. The performance doesnt really factor as much as i thought it would. I guess it comes down to the amount you can hoon on britains roads now

And before anyone suspects im not much of a driver, ive owned performance cars since i was 24 and done countless track days. I love giving a car a good ragging
I did want to scratch the ///M itch, but in reality for 90% of the time a 3.0si is the better buy. Lets wait for someone to counter this talking about the other 10% of the time! Be happy with yourr 3.0's people, they're great!
Edit: God, im of on one again, wishing i didnt have to worry about finances and early mid life crisis's!
Just depends where you are in life eh!
